If you don’t want cigarettes smoked in your home because of the smell, why would you want guests to smoke marijuana inside? It has an incredibly strong smell which lingers.
It also means that you will put the majority of guests off from staying in your place as you will have to mark it as a smoking property.
If you want to market your place as marijuana friendly then make sure you have it in your house rules that guests (and of course yourself ) smoke outside.
